12.3.6.2 Handling the thermistor faults in a COMP unit
i. ICT/OCT thermistor is disconnected or shorted -
The invalid thermistor temperature is replaced by 43oc, so that the unit
can continue the normal operation. All protections related to that faulty
thermistor will be disabled. For example, in case of any ICT fault, the ICT
high pressure protection in Heat Mode and ICT defrost protection in Cool
Mode will not operate anymore. The same is also applied to the OCT fault.
ii. RAT thermistor is disconnected or shorted –
The RAT will be derived from the ICT by using the equations :
Heat Mode: RAT=ICT/2.3
Cool Mode RAT=ICT*4
Notes:
x In case of any thermistor failure, the STBY LED will be blinking until the
fault condition is corrected.

Notes:
x As in the COMP unit, the STBY LED will be blinking to indicate a

to the following:
In other models IFAN will operate in low speed for 30 sec and then stop. If

Protects the Outdoor coil from ice formation by controlling COMP & RV operation.
Scope
This new deicer is designed to operate at extreme temp conditions. The deicing cycle
could be triggered from:
1. OCT temp and time between two consecutive deicing cycles.
2. Detection of ice forming by change of the OCT temp.
Both algorithms adjust the time between deicing cycles to optimize the A/C
performance. The algorithm will automatically increase the time between deicing cycles
and reduce the deicing cycle as needed.
The algorithm uses EEPROM data to operate.

12.11.2 Time adjustment in Sleep Mode
The user can make use of the Off-Timer to extend the Sleep Time from 7 hours to 12
hour (max). The operation of the new “Extended Sleep Mode” is illustrated by the
graphs below.
Case 1 is the Standard Sleep Mode, which is the only sleep mode in previous version
of MCU. The A/C unit simply works for 7 hours, then goes to SB.
Case 2 is the new Extended Sleep Mode. If an active Off-Timer is set to turn off the
A/C between 7-12 hour, relative to the starting of Sleep, the Sleep time is extended.
And, instead of going to SB at the 7th hour, the A/C will work until reaching the Off-time.
Case 3 is an exception to case 2. The Sleep Mode will not be extended to the Off-Time
when the Off-Timer is preceded by an On-Timer, which is also between 7-12 hour.
